Nestled in Fengjie County in Chongqing, China, the Xiaozhai Tiankeng is recognized as the largest and deepest sinkhole in the world. Often referred to as the “heavenly pit,” this awe-inspiring geological formation measures approximately 662 meters deep, with a length of 626 meters and a width of 511 meters. The Xiaozhai Tiankeng is a stunning example of karst topography, formed by the collapse of limestone over millions of years.

The Xiaozhai Tiankeng was formed due to the unique karst
landscape of the region. Over centuries, acidic water eroded the underlying
limestone bedrock, gradually creating underground rivers and caves. The
continuous erosion eventually led to a massive collapse, forming the enormous
sinkhole we see today. Researchers estimate this natural wonder is about
128,000 years old, adding to the allure and mystery of the site.
The Xiaozhai Tiankeng stands out not only for its size but
also for its unique double-tiered structure. The sinkhole has two distinct
levels, connected by near-vertical walls covered with lush vegetation. The
upper tier spans about 320 meters deep, while the lower tier drops another 342
meters, reaching a total depth of 662 meters.

Thanks to its remote location and isolated environment, the Xiaozhai Tiankeng has developed into a unique ecosystem, home to a wide range of plants and animal species. The dense forests on the sinkhole's walls provide a habitat for various birds, reptiles, and rare plant species, some of which are found only in this specific area. The flourishing ecosystem within Xiaozhai Tiankeng makes it a prime location for ecological studies and attracts biologists worldwide.
